摘要:
A multi-core processing apparatus may provide a cache probe and data retrieval method. The method may comprise sending a memory request from a requester to a record keeping structure. The memory request may have a memory address of a memory that stores requested data. The method may further comprise determining that a local last accessor of the memory address may have a copy of the requested data up to date with the memory. The local last accessor may be within a local domain that the requester belongs to. The method may further comprise sending a cache probe to the local last accessor and retrieving a latest value of the requested data from the local last accessor to the requester.
